Abstract
A random number generating apparatus is equipped with a random number memory section in which a plurality of sets of random numbers, whose total energy R, has a fixed value are stored. N random numbers are generated on the basis of more than one set of random numbers read from the random number memory section, and further multiplied by a square root of (T×M÷R÷N) to obtain a random number sequence having a predetermined energy. A normalization coefficient S can be obtained with a simple process without any usage of the calculation of division and square root multiplication, thereby enabling a small-scale apparatus to be realized. Accordingly, the random number generating apparatus has a decreased scale in the circuit arrangement capable of outputting the random numbers having a predetermined energy.
